Camping Microwave Ideas or How to Make Your Meal Hot Outdoors

A century-old wisdom of Henry David Thoreau Walden says “Heaven is under our feet as well as over our heads”. This is all about nature around us. People who enjoy morning dew, fresh cool air, logs crackling in the fire, night sky rich with stars, the rustle of tent and coziness of a sleeping bag would sacrifice the comfort of their homes to the romantic appeal of camping. The only thing they are not ready to do without in nature is a hot substantial meal.


Warming up meals during camping can be quite challenging. At home, there is a microwave to do the job while outside the house microwave is hard to be used. So what to do when you are on the picnic with no traditional kitchen gadgets? Let's face it, there are no camping microwaves. Camping presupposes minimum appliance, least possible to no energy consumption, and little efforts applied. A standard microwave oven does not correspond to above requirements, thus you can hardly find one. With that, there is a variety of alternatives how to warm up foods being outdoors. We tried to summon all the options we managed to find how you can make your meals hot while camping without a traditional microwave at hand.


Hot meal idea #1 – Use your automobile battery


Camping trips by car have their advantage – they allow to make use of devices that require electricity. For that purpose a car power inverter is needed, a device that helps to power most electrical appliance from a laptop to a microwave. A power inverter is inexpensive and easy to use. Campers often exploit it in order to plug in kitchen gadgets when no electricity is available. If you need to get hot food fast at the picnic, it is better to opt for a smaller, thus for a less power-sucking microwave. The reason is simple – a car battery runs down slower. For example, if a mini microwave is 600 W, then an inverter must be at least 800-1000 W. Let's make some calculations. If you warm up foods at 600 W for 4 minutes, this heating session will take about 40 watts from your car battery. A standard fully charged car battery (60 A/h) has a 720-watt capacity. It means that you can safely deal with a few heating sessions. But after that, you will have to start up the engine, let it idle or drive to charge the battery. Below there are some compact microwaves you can use for camping needs:


1. Whirlpool countertop microwave

If you are looking for the smallest microwave to satisfy your camping needs, this one might be a good option. It takes little space in a car trunk and does not demand a large countertop surface to be placed on. Regardless its size, you can easily place a dinner-size plate inside. Speaking about functionality, it works as it should. Due to its low energy-capacity, it won't drain a car battery so fast, unless you decide to roast the chicken.

  • Pros: very small, dinner-size plate fits in there, works great, interesting design.
  • Cons: too expensive, requires a pure sine wave inverter.
  • Item weight: 33 pounds (15 kg)
  • Item dimensions: 13.8 x 15.4 x 14.1 inches (35 x 39 x 35.8 cm)
  • Price: $151.00 BUY NOW


2. Bella compact microwave oven

This is just another microwave that can be used while camping. It is smaller than many conventional microwaves so it won't take much space. There is even a variety of colors you can choose from. But the main feature is its performance. Many users claim that with the 700-watt capacity it seems more powerful than expected. For instance, a cup of water starts boiling in less than 1.5 minutes. This microwave is good for warming up leftovers or ready-cooked meals while being camping. At the same time, you can use it for cooking (especially with some microwave cooking bags) but keep in mind car battery capacity then.

  • Pros: inexpensive, works good, small, a variety of color options, a rich set of programs.
  • Cons: tough opening mechanism, does not heat evenly.

Hot meal idea #2 – Flameless ration heaters


The idea of using exothermic chemical reaction for heating meals in picnic was taken from the US military forces. The meaning is that a small amount of water triggers the reaction without causing any flame of smoke. Even though camping does not require conspiracy, the concept is great. Heating bags are lightweight and small what is crucial when weight matters. Here are some options of ration heaters:

Hot meal idea #5 – Alternative methods


Let's go green during camping! Solar energy is 100% free and eco-friendly. Moreover, the sun is a sustainable and renewable source of energy. On an industrial level, solar energy is absorbed by solar panels, large and bulky, but this is not the case when you need to warm up foods in a sunny area. There should be a compact construction. So here is the idea of how you can stay full up in nature on a sunny day.


16. Sunflair solar oven

Why not use free energy of the sun while camping? This is what probably the engineers of Sunflair though before they showed the world their concept – a mini solar oven. Sun rays are not so fast at cooking and heating but this does not diminish the idea of a solar oven. It works faster in very sunny regions, so if you know exactly where you are going to camp and whether there will be many sunny days, you can think of buying this device. Be ready that the largest temperature it can provide is only 225 °F (105 °C), which can't be enough for baking but good for cooking eggs, small roasting and heating meals.

  • Pros: foldable, small, compact, wisely designed, heats up quickly, easy to use.
  • Cons: works only in sunny weather.
  • Item weight: 1.25 pounds (560 g)
  • Item dimensions: 11 x 5 x 13 inches (28 x 12.7 x 33 cm)

Camping essentials you may need

Regardless of what your choice of a microwave alternative is, make sure to enable yourself with helpful camping staples to make your cooking routine easier.

  1.  A box of matches and some ignition mixture. Even if you get ready for the camping by purchasing one of the abovementioned appliances, it is recommended to always have matches and a bit of a fire stimulation fluid in case of damp ground and logs. If everything you've prepared for cooking fails, you will always have a backup and will be able to start an open fire to save your dinner.
  2. Dishes necessities. Cooking during camping requires thorough preparation but outdoor events can be full of surprises. If you don't want to be struck by them unexpectedly, it would be thoughtful to take a medium to a large lightweight pot and a compact grate that you can place over fire. If weight is a great concert and a pot will add to a backpack mass, then take a piece of aluminum foil, which you can shape in a pan and cook or heat some food. You can even fry some bacon and eggs on a foiled pan in case of emergency.
  3. Tongs and gloves. These tools are meant to protect you from burns which are undesirable for campers. Pulling food off a portable stove or even a heating lunch box bare-handed is not very pleasant.

Let nothing mar your camping experience, neither the bad weather nor a lack of certain camping gear!
